ABSTRACT:
There is provided a fabric made of sheath-core type composite fibers in which the core is made of an elastomer (A) and occurs in a fineness of not less than 0.15 denier per core piece and the sheath is either made of sea-island phase whose island component is a nonelastic, fiber-forming polymer (B) and occurs in each fiber in the form of a large number of fine island pieces having a fineness of less than 0.15 denier and whose sea component is a soluble polymer (C), or made of a multilayer laminate phase with the nonelastic, fiber-forming polymer (B) and the soluble polymer (C) occurring radially and alternately. Also provided is a fabric derived from the above fabric by removal of the soluble polymer (C) in the composite fibers by treatment with a solvent. The resultant fabric comprises bicomponent fiber bundles each composed of a core fiber of elastomer (A) and a large number of ultrafine fibers of nonelastic polymer (B) surrounding the core fiber.
